Stingray (1978)

aka: Abigail Wanted

Lonigan (William Watson) and Tony (Bert Hinchman), two drug dealers, shoot two cops who attempt to set them up, and run away with a million bucks and the drugs, which they stash in a red Corvette Stingray in a used car lot. When they attempt to recover their stash with their leader, Abigail (Sherry Jackson), they find out that two happy-go-lucky dudes, Elmo (Les Lannom) and Al (Christopher Mitchum), have bought the car. They quickly pursue the two along with the police who think that the car's new owners are the criminals.
